DiE-PRESS.

SPECIFICATION forming part of Letters Patent No. 361,633, dated April19, 1887. 1

Application filed Apr-i128, 1886. Serial No'.200,-110. (No model.)

To all whom it may concern.-

Be it known that I, EDMUND JORDAN, a citizen of the United States,residing in Brooklyn, Kings county,New York, haveinvented an Improvementin Double-Action Crank-Presses, commonly used in the manufacture ofbuttons and similar light wares from sheet metal; and I do herebydeclare that the followingisaful], clear, and exact description of thesame, reference being had to the accompanying drawings, forming part ofthis specification.

The object of the invention is to secure an easier and simpleradjustment of the cuttingpunch than has hitherto been attained, and alsoto obtain a simpler, lighter, and better construction of the machine.

The invention consists, partly, in the guiding of the drawing-punch bythe cross-head, which carries the cutting-punch slide of the ter of thiscross-head and the body of a screw projecting downwardly therefrom forthe attachment of the cutting-punch slide.

The invention further consistsin a novel adjustment of the cuttingpunchslide, which consists in an arrangement of nuts relatively to saidcutting-punch slide for attaching it on the downwardly-projecting screwof the crosshead which carries it.

Theinvention further consists in the combination, with the drawingpunch, of a screw having a ball upon the end thereof fitted into asocket in the top of the drawing-punch, thus forming a ball-joint, andthe threaded part of said screw fitting into a nut on the rod end whichconnects said screw with the crankwrist that drives the drawing-punchfor the adjustment of the same, as hereinafterfnll y described. By thisarrangement the turning of a single screw is sufficient to set thedrawingpunch to any point of adjustment, and when so seated the screw isheld by a jam-nut, so that it cannot alter the adjustment.

In the drawings, Figure 1 is a front view of the machine; Fig. 2, avertical section on line a: w in Fig. 1. Fig. 3 is a section on the line3 3/ of Fig. 1. Fig. 4 is partly a front elevation and partly asectional view showing construction of details. A represents the bed ofthe machine; B, the

press, a guide being formed through the cen-.

uprights rising from the bed and terminating in an arch, C, at the top.

D is the shaft of the machine, which runs in boxes or bearings E, formedon or attached to thefrontfitcesoftheupperpartsoftheuprights. The arch Cis made to re-enforce the shaft D and strengthen it during the act ofpunching or pressing by the adjustable steadying device F, which bearsupon wheels G, formed on or attached to the shaft D centrally andsymmet- 6o rically at such distance from each other that the crank-pin-H, Fig. 2, which drives the cutting-punch,and which extends from one ofthe wheels G to the other, is of sufficient length to give ample bearingfor the rod end K of the rod which drives said punch.

L is the screw which connects the rod end K with the drawing-punch M,and which, together with the rod end K, may be considered as a shortconnecting-rod, the rod end K being formed in any suitable manner forembracing the crank wrist H and connecting said punch with thecrank-wrist. From the lower part of the rod end K projects a nut,

N, into which the screw L is fitted, as shown sectionally in Fig. 1. Thebody of the screw L has on it a boss, a, shaped to receive a suitablewrench for turning the screw L, and upon said screw is also fitted ajam-nut, b, for bolding the screw L in fixed adjustment after it hasbeen adjusted in proper relation with the cutting-punch slide. At thelower part of the screw L is a ball, a, which is fitted into a socket inthe upper end of the drawing-punch M, and is held to its place by meansof a nut, d, screwed down over said ball upon a thread formed on theupper end of the punch M.

O O are two connecting-rods, which connect cranks exteriorly adjacent tothe wheels G with the cross-head P, which carries the cut- 93 ting'punchslide Q. There is nothing peculiar in the constructionof these rods, andtherefore they need not be further described. Their lower ends areconnected to trunnions R, formed on the cross-head P. The central partof the 5 cross-head is rectangular in horizontal crosssection, as shownin Fig. 3, and during the act of punching or pressing it presses againsta guide, S, which has a vertical bearing-surface, against which the rearof said rectanguroe tension. The collar 9 is fitted to pass easily-'head is to press toward said guide.'

Projecting downward from the rectangular body of the cross-head P, whichhas been described, is a hollow screw, T, Figs. 1 and 2. Thecuttingpunch slide Q is provided with two upright extensions, f, Figs. 1and 2, conmeeting the body of the cutting-punch slide Q with a collar,at the upper part of said exbut accurately over the exterior margins ofthe screw-threads on the screw T, and is held in relation with the screwT by means of nuts 1:, one above said collar and the other below thesame. By means of these nuts said collar may be adjusted to any properrelation with the screw T.

Through the cross-head P and its downwardly-projecting-screw T is formeda cylindrical guideway, 7c, in which guideway the drawing-punch M isnicely fitted to slide vertically. The cutting-punch slide Q runs in thelateral guides Z, which, together with the guide-plate S, accuratelyguides it in its vertical motion; and it is evident that, when it is soguided, the motion of the drawing-punch M must be also accurately guidedin its vertical motion. 7

m m are set-screws for setting up a gib to take up the Wear in theguides of the cuttingpunch slide Q.

n a are strengtheningribs which help to support and strengthen thesupports B.

Besides providing means for very simple adjustment of the drawing-punch,(only one screw having to be manipulated instead of two, as-heretofore,and hence only half the time being required to perform the adjustment,)it will be seen that the construction described results in a very simpleand effective machine.

The cuttiug-punchis shown at Q in Fig. 4.

In its descent it coacts with the cutting-edge q of the die Q to cutfromthe metal to be punched the blank which is to be shaped by theaction of the drawing-punch and the lower part, q, of the die Q in amanner (shown at q) well known tothose skilled in the art, and

which need not, therefore, be more fully described.

Having thus described my invention, what I consider new, and desire tosecure by Letters Patent, is as follows: 7.

1. The combination, with the cutting-punch slide of a doubleactingcrank-press and the cross-head carrying said cutting-punch slide,

'and having a central vertical guideway formed therein, of adrawing-punch working in said guideway and guided thereby in relation tosaid cutting-punch slide, substantially as and for the purposespecified.

2. The combination, with the cross-head of a double-acting crank-presshaving formed thereon the downwardly -projecting hollow screw T, uponwhichis clamped or fastened a cutting-punch slide, Q, and having acentral guideway, 70, passing through the body of said cross-head andthrough the barrel of said screw, of a drawing-punch, M, guided in duerelation with the said cross-head, screw, and

cutting-punch slide by said guideway, sub-v stantially as and for thepurposes described.

3. The combination of the cross-head P, carrying the cutting-punch slideQ and having formed therein a central vertical guide way, loathedrawing-punch M, the screw L,

connected with the upper end of said punch by a ball-and-socket joint,and the rod end K, having formed therein a female screw for thereception of the male threaded portion of the screw L, for adjustingsaid punch, substantially as and for the purpose specified.

EDMUND JORDAN.
